4.1 Things to Know before Connection

Warning
The connected or built-in peripherals with opposite polarities are not allowed.
Warning
The device only operates when connecting with grounded power. No operation is
allowed when the device power is ungrounded or only impedance is grounded.
Warning
Rated voltage of the device in use shall be in accord with power feature of the
product.
Note:
Only the peripheral devices approved for industrial application can be used. When
operating the PC, hot swappable IO modules (USB) can be used. The IO devices
without hot swap function can only be connected when the PC is powered off.

4.2 Product Grounding

Low impedance ground connection is more helpful to release the interference
produced by the external cables, the signal cables or the cables connecting the IO
module to the grounding system.
Ground Terminals
The equipotential bonding terminal
the device shall be connected with the
cabinet installed with the PC or the
central grounding busbar on the device.
The minimum cross section area of the
cable shall be no less than 2.5mm
maximum ground resistance should be no
more than 0.1Ω.
